I don't know a lot about this JavaFX, but me I work with eclipse, and I'd like to know is this JavaFX, easy to integrate in eclipse environment or other JAVA IDE.
Other things, is javaFX mature to be user in business application.
I have tried using JavaFx plugin for Eclipse. I faced a problem while getting it to work. I had to change over to NetBeans. If you use NetBeans you do not have to worry about adding plugins. You can select the JavaFx package and it comes ready with NetBeans.
